INSTALLATION 1. 2. 3. 4. 5. 6.
Locate the wall-plate in the mounting position, insert the mounting screws through the appropriate holes, and screw into position. Complete the wiring. Attach the thermostat to the wall-plate as follows: Locate the 4 side slots on the wall plate into the appropriate slots on the back of the thermostat. Press down firmly and snap the thermostat into place. Tighten retaining screw in lower edge of thermostat.
Wiring the thermostat
The standard wiring access is via a hole in the centre of the thermostat wall-plate.
Removing the thermostat from the wall
If it becomes necessary to remove the thermostat from the wall-plate:
Location
1. 2.
The T6590 Series thermostat is the temperature control element in the fan-coil or air-conditioning system, and must be located about 1.2 to 1.5m above the floor (according to local building regulations) in a position with good air circulation at room temperature. Do not mount it where it could be affected by :-
3. 4.
draughts or dead spots behind doors or in corners hot or cold air from ducts radiant heat from the sun or appliances unheated (uncooled) areas such as an outside wall behind the thermostat concealed pipes or chimneys
5.
Mounting the thermostat
Any T6590 Series thermostat can be directly mounted on the wall or horizontally on either a 65x65mm standard junction box or a 2x4inch US junction box. Mounting screws are supplied for both alternatives. IMPORTANT The installer must be a trained service engineer Isolate the power supply before beginning installation
3 EN0H8579 R0 2009
Isolate the power supply before removing the thermostat. Loosen the retaining screw in the lower edge of the thermostat. Pry the lower edge of the thermostat away from the wallplate. Use both hands to pull the thermostat straight away from the wall-plate. NOTE - Incorrect removal of the thermostat from the wall-plate may damage the device.
